Arrhenius Acid Definition: Hydronium breaks up to yield an H+ in solution. Arrhenius Base Definition: Hydroxide is an OH-dissolved in water. Bronsted-Lowry Acid Definition: Hydronium is an H+ donor regardless of solution. Bronsted-Lowry Base Definition: Hydroxide attacks and accepts the H+ from hydronium.Lewis Acid Definition: The H+ on Hydronium accepts the attacking electron pair to form a bond.ronsted-Lowry Acid Definition: Hydronium is an H+ donor regardless of solution.

It is believed that the first Ancient Chinese fire works were made in Han Dynasty (206 BC-220 AD). Fireworks in Ancient China were originally used for shows, christenings and special funeral ceremonies.
